the deeper I dig the more it seems that it's a documentation anomaly. I 
looked in perforce and found where it disappeared.

I version 3.5 colors.inc had 7 revisions ... initial version 2/21/01 
didn't have /ANY/ color macros but showed up in v2 when CHSL2RGB() and 
it's kin, including Convert_Color() were added. In version 5 
Convert_Color() was removed and hasn't been heard from since ... the 
others remained.

I'm going to remove it from the documentation.
